Thanks all for your answers. The problem was solved by using -cifti-label-import. Sorry for bothering. Here I have another question: I have a label file *.dlabel.nii (created by thresholding the *tfMRI_MOTOR_level2_hp200_s4.dscalar file, in my previous question) I print the information of this file to a txt file, and find there are 14326 nonzero labels.I'd like to change this file into a normal nifti file in mni space, so that I can use it as a roi region for fiber tracking, I use the command "-cifti-separate -volume-all "and change it into a *.nii file, but when I read the file, I find there are only 3256 labels. I dont know why some labels are discarded.

You can use wb_command -cifti-merge to extract frames, though it is not as convenient as something like fslroi would be as you have to specify each frame. Peace, Matt.
